5 Animal Track Patterns to Spot This Winter

December 11, 2024

Ever since November, when snow fell in Bloodvein River First Nation and was here to stay, Guardian Melba Green has been following animal tracks to gain clues about their winter activities, habitats, and movements.

“It’s good to see tracks. It means the animals live here, too, and walk among us. They are exploring and hunting. They roam alone or in packs.”

Tracks are intriguing

“I like to think about what the animal was doing and why, based on its tracks,” Melba says.

Tracks might tell you if a fox chased a hare, whether the hare reached safety, or if a kill was made. Sometimes you can see that an animal has sped up in the snow, suggesting it was spooked. Some tracks leave you wondering. Such as, why did the squirrel turn around and head back up the tree? Did it sense a predator nearby? Or, what is this mark in the snow beside the lynx tracks? Was the lynx dragging prey from its mouth?

“It’s best to go tracking after a snowstorm,” says Melba. This is when snow is fresh and animals are out in search of food. “Old tracks are harder to identify.”

Look for tracks when snow is fresh.

Track Patterns

Melba notes that different animals move in different ways. The animal’s track pattern is the biggest clue and first thing she looks for, she says. Here are five track patterns to spot this winter.

Identify the track pattern first.

1. Hoppers

Snowshoe hare, mouse, red squirrel

The snowshoe hare’s back legs swing forward as it hops

Hoppers usually have back legs that are bigger than their front legs. When the animal hops, its front feet land first, then its back feet swing forward and land in front of the front feet.

What to look for: Clumps of four prints

2. Bounders

Mink, otter, marten, weasel

Weasel in mid bound through snow. The weasel lands on its front feet. When it bounds forward again, its back feet will land where its front feet currently are.

Bounders usually have long bodies and short legs that are all the same size. When the animal moves forward, its front feet are down. In a single motion, it lifts its front feet and pushes off with its back feet. The back feet land almost exactly where the front feet were.

What to look for: Two prints side by side, with one print slightly in front of the other (it looks almost as though the animal was hopping on two feet)

3. Waddlers

Bear, beaver, muskrat, porcupine, skunk, woodchuck

Waddlers usually have short legs and shift their bodies side to side as they walk, dragging their bellies. Their front and back legs move together one side of their body, then the other side. All four prints land in separate spots.

What to look for: A front and back print next to each other, on each side

Bear tracks with lines showing how its body sways side to side as it walks/waddles.

Bears occasionally wake up and move around during winter.

4. Zig-Zaggers

Lynx, fox, moose, timber wolf woodland caribou

Zig-zaggers usually have long legs. When the animal moves forward, the print from its back foot lands on top of (or very close to) the front print.

What to look for: Single tracks in a straight or slightly zig-zagged line

Lynx are zig-zaggers, also known as perfect walkers – they step on top of their own tracks

5. Snow Angel

Eagle, owl

Birds of prey touch down to capture their prey. You can usually see the tracks of a small mammal moving toward the print and messy snow in the centre of the print, where the bird gripped the prey with its talons.

What to look for: Wing, tail and talon marks, and tracks made by prey

Track Like a Guardian!

What animal made the tracks you see? Once you identify the track pattern, ask yourself these 10 questions to narrow down your list:

What animals live in the area?
Where are the tracks—such as an open area, riverbank or forest—and what animals tend to inhabit or travel through here?
What shape is the track?
How large is the track?
Does the animal have webbed feet, hooves or foot pads?
How many toes do I see?
Does the track have claw marks?
Is the track deep or shallow (the heavier the animal, the deeper the tracks)?
Is scat nearby and does it tell me if the animal is a plant eater (pellet-like scat) or meat eater (tube-like scat)?
Are there any other clues, like multiple tracks indicating that the animal travels in a pack or herd, fuzzy tracks caused by fur between the animal’s toes, or signs of a tail dragging through snow?

The Challenge of Identifying Animal Prints in Snow

Animal prints in snow are often unidentifiable—they may be too deep, fuzzy, melted, blown over, or lack detail—but it’s still fun to look for clues and do your best to narrow down which animals walk among us. Enjoy spotting track patterns this winter!

Why Award-Winning Nature Photographer Ōtake Hidehiro Keeps Coming Back to Pimachiowin Aki

December 18, 2023

Growing up in the busy city of Tokyo, Japan, Ōtake Hidehiro (Hide) had never truly experienced being deep in nature. However, an eye-opening camping trip during his university days sparked his profound connection to the natural world and ultimately led him to the people and land of Pimachiowin Aki.

We recently sat down with Hide in Winnipeg to talk about his journey.

Your camping trip as a member of mountaineering club was pivotal. You said it was the first time you realized that the environment you grew up in was human-built.

It opened my eyes to the natural world far away from cities. That’s the first moment I really loved it. Because I’m not a factory-made robot; I was born as part of nature. We set up a tent and slept under a sky full of stars. We lit a fire and fished stream trout. There was no running water or electricity. So I really loved the simple camping life and began to notice how beautiful this planet is.

The camping experience steered you away from your initial career choice and guided you toward nature photography.

Yes. At that time, I wanted to be a journalist, but I thought, oh, I really care about nature instead of the economy and politics. I have skills to explore the woods and mountains, so I really want to tell the story of spiritual nature, which probably won’t be in the newspaper. But it’s very important.

I became a photographer because I wanted to be in nature.
Ōtake Hidehiro

So how did you get your start as a nature photographer?

I bought my first SLR camera at the end of my third year of university, but I was struggling to find my first theme. Then, I had a dream. I was in a small cabin and snow was falling. A creature came in and we looked at each other. It was like a big dog. Whoa! But it’s too severe. When I woke up, I thought, oh, a wolf came; I saw the wolf walking in my dream.

Until that dream, I had never even considered wolves as a topic. Wild wolves had vanished from Japan over 100 years before.
Nippon.com, Photographer Ōtake Hidehiro: Following the Dream Wolf

I wanted to learn more about the wolf. I went to the library the next morning and found a beautiful portfolio taken by world-famous National Geographic photographer Jim Brandenburg. There’s a wolf. And it’s beautiful. And it’s in the woods. It looks like my dream. So I thought, I really want to go where this photo was taken, and meet Jim to learn photography under him as an assistant.

[Jim] answered my request with gentle refusal, saying that he did not need an assistant. However, he saw my sincerity, and offered a compromise. He told me, “It’s important to face the natural world alone. Good work takes time, so you should start shooting now.”
Nippon.com, Photographer Ōtake Hidehiro Finds His Path Forward

Your decision to travel to Ely, Minnesota to meet Jim in 1999 marked the beginning of your decades-long exploration of the Northwoods wilderness of North America. You recently published a photo book celebrating 20 years of work, including photos taken near and in Pimachiowin Aki.

When my publisher agreed to produce a photo book, I wanted to show four things: the northern landscapes, various wildlife including the elusive wolf, the joy of adventure of canoeing and snowshoeing, and the First Nation way of life on land. The book has about 180 photos. Three photos of wolves were used – a lone wolf watching me from the distance, an aerial shot of wolves walking on a frozen lake, and a wolf pack feeding on a deer, which shows their behaviour and interaction.

What sets your work apart is not just the visual beauty but your deep engagement with Anishinaabeg who steward this land. A turning point in your career came in 2010 when you were invited to a Healing Camp on the shores of Weaver Lake at Poplar River First Nation.

Yes. Before then, I heard a little bit about the World Heritage project because I lived in Red Lake, Ontario for over a year between 2005-2007. I wanted to go to the Healing Camp to take pictures and learn. I met lots of people from Poplar River and other communities. After the Healing Camp, I took a flight to Little Grand Rapids and Pauingassi and people showed me around. It was just a short visit. I really wanted to spend more time there.

Getting to know the First Nations people who still maintain tradition as hunters and gatherers in this land finally gave me a new perspective on the trips I was taking.

You have traveled to this region numerous times since. What keeps bringing you back to Pimachiowin Aki?

Culture is a very interesting thing for me. Before, I thought this place is wilderness; there are not many people. But I realized after my experience of learning from Elders and archaeologists, oh, this is a place where people have lived for thousands of years. Pictographs and a piece of pottery or stone tools can be found in places. I really want to tell the story about how they are connected to the land.

You are drawn to the stories embedded in the landscape…

Yes, now I look at the landscape and understand that it’s not just forest or water. I can feel the history of the land. When I was traveling by canoe in Pimachiowin Aki, I found many pieces of pottery around my campsite. When I showed a photo of it, an archaeologist told me that the site has been used for at least for more than two thousand years. I remembered there’s a waterfall nearby. It’s a good place to get fish. There’s a nice sandbar, so maybe it’s a good landing spot for canoes for hunting. You can walk through a nice hill, which has lots of blueberries or medicines.

I want to take photos to show it’s the wildlife’s homeland too. To get a good photo of wildlife, you have to know their behavior and lifestyle. Like that squirrel. That’s his house and he has probably never seen people before, so he was kind of getting nervous. He’s busy collecting the pinecones to survive the winter. I should be quiet and respect his space because I am just a visitor to his homeland.

So that’s a very important part of this place. I really love that Pimachiowin Aki gives me a lot of opportunities – not just wildlife and landscape and camping, you know, there’s always people there to teach me and so many things I can do, and so many places I haven’t seen. I’m not just coming here to take pictures and sightsee. I want to actually learn and experience the processes of living with nature. Most people living in cities have lost that connection and wisdom.

It seems only natural that I would be even more drawn to the lifestyles and culture of the Indigenous Peoples who had coexisted with this natural environment for so long.
Nippon.com, Ōtake Hidehiro Learns More Lessons of the Life Giving Earth

Your work reflects on our connection to nature, appreciates its fragility, and recognizes the responsibility we all hold to preserve it. But for many people, life is far removed from nature. What does it mean for you to connect with the natural world?

When you’re camping or traveling by canoe or snowshoe, you can feel a very deep connection to nature because you can feel wind, water and snow closely. And you can even get a fish! That’s local food. And it’s a gift from nature. So you can appreciate it more.

If you hold a paddle you can feel it grab the water. You feel the connection. And once you get on the shore, it’s nice. It makes me very happy, right? It’s like a welcoming. Just to stand on and touch it and say thank you very much for this nice landing.

And when I drink water, it connects me to nature. Sixty per cent of my body is water, so more than half of my body is from this lake. I don’t want to pollute it. So those connections—the connection with a tree—you start feeling like the tree is a friend. And even dead trees can become a good friend when you’re cutting up firewood. They make you warm. I appreciate that very much.

Cultural experiences, like learning from Elders and participating in net fishing and collecting medicine plants, have deepened your appreciation for Pimachiowin Aki. You were here this fall and spent time with Pauingassi First Nation Guardian Colin Owens and his wife Cora.

It has been great to see their lifestyle of living off the land!

What’s next for you in Pimachiowin Aki?

I would like to learn about seasonal activities and am interested in photographing life on the land throughout the year. So, spring duck or geese hunting, winter trapping for beaver and snowshoe hare would be interesting subjects.

Colin is interested in showing me how to snare snowshoe hare and catch fish by net under ice, and I would love to photograph it.

Your commitment to promoting awareness of Pimachiowin Aki extends beyond photography. You give speeches and presentations in Japan and North America and have even led tourist groups from Japan to parts of the boreal forest that touch Pimachiowin Aki.

In 2013, I took a school group to Red Lake, and in 2018 and 2019, I took two groups of people from their 20s-70s. They said it was one of the best trips ever. Just seeing a wolf track on sand or mud was a very special experience because it is now impossible in Japan! They could see the natural beauty but also experience the lifestyle connected to the land.

Is there anything more you’d like to share with the people of Pimachiowin Aki?

Photo: Ōtake Hidehiro, jackpine forest 10 years after a fire

Before, I didn’t pay much attention to my own culture. But when I’m experiencing the different culture, I am learning my own culture. Being proud of my own roots makes me stronger. Everything has a spirit in nature – I’ve grown up with that in my culture, too. And I feel the connection. I’m not born here. I’m not living here. But I really want to learn about this area. So I hope people look at their culture, the precious lifestyle and traditions you have, and are proud. It’s really wonderful. And it’s very important for all of us.

Songmeter Project – First Results Are In

March 21, 2023

Thank you to contributors Councillor Eddie Hudson, Poplar River Lands Guardians Norway Rabliauskas and Brad Bushie, Dr. Jeff Wells, and Elisha Corsiga (writer)

Our Elders and their ancestors have cared for our Traditional Lands for over 6,000 years.

Protecting Pimachiowin Aki, which over 200 bird species rely on for survival, is an important example of how we care for the land,” says Poplar River First Nation Lands Councillor Eddie Hudson.

Since 2016, Poplar River Lands Guardian Norway Rabliauskas has been collaborating with scientists from Audubon’s Boreal Conservation program to better understand how songbird populations are changing in the face of climate change.

The first results of the ‘Songmeter Project’ are in.

“Songmeters record bird sounds,” says Guardian Brad Bushie, Poplar River Lands Guardians Program. Using knowledge of the land, Poplar River Lands Guardians placed the recording units at four sites across the traditional territory, he explains.

The number of bird species recorded allows us to analyze population changes over time,” adds Dr. Jeff Wells, Vice President for Boreal Conservation at National Audubon Society.

Guardians placed Songmeters in four survey sites in Poplar River First Nation throughout the spring of 2016

71 bird species were detected

At least 18 of the species detected have more than 70% of their breeding range confined to the Boreal Forest biome, meaning their survival relies heavily on healthy landscapes like Pimachiowin Aki

Two species were detected on more than half of all recordings:
- White-throated Sparrow
- Swainson’s Thrush

Five species were detected on more than 30% of all recordings:
- Blackburnian Warbler
- Ovenbird
- Song Sparrow
- Bald Eagle
- American Crow

At least 20 species listed as special concern, threatened, or endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) are believed to occur within Pimachiowin Aki. The Songmeter project captured recordings of three of the bird species listed by COSEWIC:
- Common Nighthawk
- Eastern Whip-poor-will
- Canada Warbler

National Audubon Society’s recent study, Survival by Degrees, found that over two-thirds of North American birds are moderately or highly vulnerable to a global average temperature increase of 3°C by 2080. This includes many species detected at Poplar River First Nation, such as:
- Bay-breasted Warbler
- Cape May Warbler
- Canada Warbler
- Blackburnian Warbler

How the collaboration began

“We first talked with the Guardians and community, and asked if they would be interested,” says Jeff.

Norway says the project is a good fit for his community. “One of our goals is to develop new research partnerships. Plus, the project builds on the monitoring work we have already been doing.”

Indigenous Knowledge and Western Science come together

The Songmeter project relies heavily on Guardians, and the process of collaborating starts with listening and respect.

Listening to Guardians’ advice is crucial in a project like this, where Indigenous Knowledge and Western Science combine to create strong, respectful conservation efforts, says Jeff. “Things always overlay with Indigenous knowledge.”

Guardians serve as stewards and scientists and are central to a program that pairs data collection with Indigenous ecological knowledge to track changes across the site over time.

Guardians have a good understanding of the land and decide where to install Songmeters.

“Our Guardians’ hard work and understanding of the land have contributed to the project’s success,” says Councillor Eddie Hudson. “We are proud of the work they do.”

*Guardian Norway Rabliauskas installs a Son*gmeter.

The project continues

This past year, Guardians installed Songmeters in the same four locations as 2016. The 2017-2021 recordings have yet to be formally processed but since the start of the project, the number of species the team has identified has “greatly expanded,” Jeff says.

Thousands of hours of song

Analyzing bird sounds can be a difficult and time-consuming task.

“What happens with this kind of work is that you can get thousands of hours of recordings, and you can imagine someone sitting down and listening… You can only get through so much,” says Jeff.

The relatively small team picked random samples, listening to four 10-minute recordings from each day collected in 2016.

187.3 hours of recordings were sampled between May 27 and July 1, 2016

New technology to speed up the process

Recently, the team implemented BirdNET in their identification process. BirdNET is an artificial intelligence algorithm developed by the Cornell Lab of Ornithology. This bird identification machine can quickly go through recordings to identify specific bird species.

The team will use BirdNet to help identify the recordings taken in Poplar River First Nation from 2017–2021.

Looking forward

In the upcoming year, National Audubon Society and Poplar River First Nation Lands Guardians Luke Mitchell, Brad Bushie and Youth Guardian Aiden Heindmarch will work together to expand the areas where Songmeters are placed. They plan to set up Songmeters in deeper and more remote areas of the forest.

“One place takes a couple of days to get to by boat,” Jeff says. “It’s exciting to see what we might find in these places.”

He hopes that over the years more First Nation communities can use Songmeters when developing their monitoring programs. He also hopes for more collaborative initiatives with communities in Pimachiowin Aki.

“If that’s what communities want to be a part of,” he says, “there are a lot of interesting things to discover.”

How 4 Wildlife Species React to Forest Fires in Pimachiowin Aki

June 27, 2022

Last summer over 130 fires roared across Manitoba, causing as many as 1,000 people living in Pimachiowin Aki to evacuate to Winnipeg. While fires can negatively impact people living in the area, some wildlife species thrive.

Forest fires are an inevitable part of the boreal forest life cycle. They are as crucial to forests as sun and rain.

As the upper canopy of trees burns, the forest floor receives more sunlight and water, allowing different species of trees, plants, insects, and wildlife to settle in.

While some species adapt to changing landscapes, others struggle. We look at four species in Pimachiowin Aki and their responses to increased fire frequency and intensity:

1. Wolverine

Wolverines are an elusive species and largest member of the weasel family. They travel long distances (especially males) and live in small packs far from civilization. They’re carnivores and scavengers, relying on other animals for food. They are ferocious predators and prey mostly on small mammals like rabbits. They also eat carcasses of large animals like boreal woodland caribou when other food is scarce.

“They eat whatever they can find,” says Guardian Dennis Keeper, Little Grand Rapids First Nation. “They eat snowshoe hare, so they’re found where the highest population of rabbits are.”

What happens to wolverines after a forest fire?

When a fire rips through a forest, it burns food sources for many species, including boreal woodland caribou. Without lichen, caribou move on in search of this favoured food source. Wolves follow closely behind, leaving wolverines to hunt for themselves.

Despite their ability to travel long distances and lack of dependence on a particular habitat, wolverines struggle when their livable territory burns. Forest fires force wolverines closer together, increasing competition for food and territory. These tough animals are incredibly territorial and turn on each other. They fight over territory, food, and females.

In Ontario disturbances could pit the few hundred wolverines against one another. They really beat each other up.
Wildfire researcher Matt Scrafford discusses negative effects of wildfire on wolverines in a 2021 CBC interview

2. Snowshoe Hare

When wildfire burns through the boreal forest, it allows plants on the forest floor to reach sunlight and grow, providing ample opportunities for hares to hide and raise their young in shrubs and undergrowth. Their numbers are known to exponentially rise in a younger forest. In fact, snowshoe hares fare better when living away from mature forests. As maturing jack pine leaves become harder to reach, hare populations decline.

Hares eat smoked leaves in nogoomekay akisakeytek (newly burned areas).

Guardian Dennis Keeper stayed in Little Grand Rapids First Nation to monitor last year’s wildfires. He has been documenting hare populations in Little Grand Rapids First Nation and reports that hare populations are abundant.

Hares usually spend daylight hours sheltered under bush, stumps, or logs and become more active after sundown. Even when sleeping or grooming, they remain alert for predators like marten, lynx and fisher, which travel from old growth denning sites to burned areas to hunt hares.

“Many wildlife species eat hare,” Dennis says. The wildfire that burned through Little Grand Rapids in 2018 has already regrown with shrubs, ideal for snowshoe hare to live and raise their young. Predators will follow. “There’s always predators right behind them, like lynx.”

3. Lynx

Canadian lynx prefer habitats with old-growth trees and little to no brush on the forest floor. However, they live in places with new growth—like a fresh forest after a fire—if it has abundant food.

“You won’t see lynx because they are shy and elusive,” says Guardian Dennis Keeper, who grew up in Pimachiowin Aki and is an avid hunter and trapper. Though Dennis has seen “only a few” lynx in his life, he knows they’re around. “I see their tracks,” he says. Plus—where there’s hare, there’s lynx.

Abundant hares attract lynx to regenerating forests—snowshoe hare is the lynx’s main source of food. The more hares in an area, the more lynx that arrive to eat them. This is called the hare-lynx cycle.

The hare-lynx cycle is part of forest regrowth, but it doesn’t last forever. The more hares lynx eat, the fewer hares there are left to feed on. Plus, as new forest grows taller, twigs, buds and needles are out of hares’ reach. Now, both lynx and hares have less food. As hare populations dwindle, lynx populations also decline.

The hare-lynx cycle lasts 8-11 years.

4. Black Fire Beetle

Wildfires don’t destroy everything. In fact, they are source of life for black fire beetles, which fly to forest fires in great numbers and mate while fires still burn.

The black fire can detect heat from forest fires burning between 50 and perhaps as far as 130 miles away.
academic.oup.com

Jordan Bannerman, Instructor II, Department of Entomology, University of Manitoba explains, black fire beetles have infrared sensors on their thorax that allow them to detect heat emanating from fires (Reference). “Heat produced from even a small fire is sufficient to attract them,” he adds. “They can also detect certain chemicals emitted from burning wood that are present in smoke.”

Females deposit eggs under the bark of dead and dying coniferous trees, leaving larvae to safely develop and hatch with few predators around. “Egg laying has sometimes been observed in trees that are still smouldering,” says Jordan.

He says that “a dying tree will also have weaker defences and be more or less free from competitors, which provides the black fire beetle with a big advantage.”

Most predators leave burned areas, but black-backed woodpeckers stick around to feast on the black fire beetle’s wood-eating larvae and other wood-boring insects, which thrive on burned boreal trees.

Do black fire beetles help or harm boreal forests ?

Jordan says, “these beetles are beneficial in that they are important primary decomposers that play a role in forest regeneration.” Black fire beetles start the decomposition process early, setting the stage for other insects to further break down the dead matter and release nutrients into the soil.

Wildfire sets a lot in motion in the boreal forest. Take a look at this 100 year-cycle:

https://pimaki.ca/the-land-that-gives-life/wildfire/

Pimachiowin Aki is the largest protected area in the boreal shield ecosystems of North America. It is 2,904,000 hectares of natural habitat for plants to thrive and wildlife to eat, shelter, and raise their young.

New Eye in the Sky

December 20, 2021

Birds have always been an eye in the sky above Pimachiowin Aki. Now, thanks to drones provided by environmental consulting and research firm ECOSTEM, Pimachiowin Aki Corp. has an eye up there too.

We are working with ECOSTEM to map land and water habitats in Pimachiowin Aki as well as tangible cultural features found mainly along major rivers in the area. At 29,000 square kilometers, Pimachiowin Aki is simply too large to ‘see’ from the ground. Each drone, and its pilot are giving us a close-up look at areas we want to know more about.

“The project will enhance our understanding of Pimachiowin Aki and provide a baseline for monitoring,” says Pimachiowin Aki’s Executive Director. “Our monitoring program is part of how we fulfill our responsibilities as a UNESCO World Heritage site,” she adds.

Working with ECOSTEM will also allow us to bring all data we have ever collected into one place—a digital map of Pimachiowin Aki. People will be able to search the map for answers to questions like: Where do lake sturgeon spawn? What areas have been affected by wildfire? Where are the best places to find blueberries?

*Drones are used to help map wildfire history, ecosystem health, and effects of climate change*.

What exactly are we mapping?

Habitat Mapping	Cultural Feature Mapping
Land habitats such as forests and grasslands, wildlife habitats such as caribou calving areas	Archaeological sites such as places where stone was collected to make tools
Water habitats such as rivers, wild rice, and wildlife habitat such as lake sturgeon spawning areas	Harvesting sites such as hunting and fishing areas, traplines, and berry and medicine plant gathering areas
Parts that form each habitat such as plants, soil and rock	Cultural sites such as cabins, campsites and petroforms

Collecting Data from Soil to Sky

ECOSTEM collects vegetation, soil, and environmental data from plots

Mapping is like taking inventory—in this case, identifying the location, number and kinds of habitats and cultural features in Pimachiowin Aki. ECOSTEM is taking inventory by going out on the land and water to collect samples and take photos and notes. The drones are capturing photos and video.

ECOSTEM Senior Ecologist Dr. James Ehnes says that the ECOSTEM drones collected “about 9,000 photos and 37 minutes of video” of Pimachiowin Aki this fall. “We had planned to capture considerably more photos and video but were unable to do so due to Covid restrictions, wildfire-related travel bans, loss of logistical support in communities that were evacuated, and extremely low water levels on rivers.”

Once we have our complete ‘inventory,’ Pimachiowin Aki can track changes over time. This is where monitoring comes in.

Monitoring is like giving Pimachiowin Aki a regular checkup—we will compare new information with our original inventory to keep watch on Pimachiowin Aki’s natural and cultural health. This will help us make sense of any changes and predict and prepare for any threats.

Project Q&A

We gained insights on the project through an interview with Dr. James Ehnes of ECOSTEM:

Your work with Pimachiowin Aki began in 2011 when you completed an ecosystem analysis to show how the area met UNESCO World Heritage criteria for outstanding universal value. What is different about the work you are doing today?

The ‘feeling’ has changed from conducting an academic exercise to having the opportunity to serve Pimachiowin Aki, its partner communities and local people. The work that we are now doing is focused on providing data, information, maps and other things that will support the continuation of Ji-ganawendamang Gidakiiminaan.

Pimachiowin Aki Guardians are the eyes and ears of Pimachiowin Aki. How does this project enhance their work?

Guardians can only cover a small area each year. The project immensely expands the area where information is obtained and can prioritize areas that we should go to get more information.

How are Pimachiowin Aki Guardians and Elders involved?

Land use information from Guardians and Elders is extremely important for cultural and natural features mapping, such as where are the best places to go to find certain plants and animals, where are notable culture features and sites located (e.g., petroforms, meeting areas, hunting areas, wild rice plantings, controlled burns, spiritually significant areas). We hope that the information that is passed on will contribute to maintaining the memories of the people and communities.

What will data you collect tell us about Pimachiowin Aki now and over time?

Most fundamentally, it will tell us what vegetation, wetlands, landforms, waterways, etc. occur within Pimachiowin Aki at a much higher level of accuracy and detail than is available now. It will also:

Show a local person new places where they could to go to find things that they want to gather or hunt
Identify important habitats for species of high interest such as caribou, moose, and sturgeon
Aid in making reliable predictions about species that are important to local people or conservation
Contribute to safeguarding and recovering species of conservation concern within Pimachiowin Aki. Examples: data may result in expanded woodland caribou research and opportunities to research lake sturgeon
Detect and monitor the spread of invasive species
Show people how their traplines have been affected by wildfire
Identify areas that were burned more severely than usually happens—vegetation recovery may be limited, and it could be evidence that important, adverse climate change effects are happening in Pimachiowin Aki
Help us study how Pimachiowin Aki is responding to climate change
Show us areas that store the most carbon, areas that are most susceptible to releasing greenhouse gases as the climate warms, and the best places to do climate research
Inform us if climate change is making fire effects worse, which has future consequences for what will be found on the land and in the water
Contribute to fulfilling UNESCO World Heritage monitoring requirements

How exactly do you collect information for the maps?

We collect information in two ways. We get information for the entire site from satellite imagery and information that has been created by others (e.g., elevations). We go out on the land and water in Pimachiowin Aki and take photos and notes. Sometimes we do this from planes and other times while boating or walking. While on the land, we collect plot samples and use drones to collect photos and video.

What is plot sampling and how is it done?

We collect habitat data in plots, sometimes with a community member and sometimes on our own. For our work so far, this has been a 40 by 40 metre square plot. Within this plot, staff collect plant, vegetation, soils and environmental data. A botanist collects plant and vegetation data by walking through the plot and recording what they see. A soil specialist collects soil data by first digging a narrow hole about 50 cm deep, then using an auger to go down to about 100 cm and pull up material that is examined and used to describe soil conditions.

We try to leave no trace that we were there. When we’re done, we fill the hole and replace the surface ‘divot’ that was carefully removed before digging the hole.

Why has the drone collected more photos than videos?

We focused on photos because we expected that they would be more useful for creating the habitat map for the entire site. An advantage of photos is that they can be ‘stitched’ together to create an image that shows a much larger area. The stitched image from the drone is more magnified than Google Earth. We may lean more towards video when documenting cultural features along waterways or habitats for species that are especially important to local people.

How does monitoring a habitat make it possible to reliably monitor a species?

A species’ habitat is the most important thing that determines how many individuals of that species can exist within Pimachiowin Aki, and where they are likely to be found.

Using moose as an example, areas that have burned in the past five to 15 years tend to provide considerably more moose food per hectare than other areas. If the proportion of Pimachiowin Aki area that has burned in the past five to 15 years goes up, the number of moose can also increase.

Using sturgeon as an example, this species has very specialized conditions for spawning. By mapping spawning conditions, we can identify areas that should not be disturbed by human activities. We can also use the mapping to identify locations that are good candidates for restoring suitable sturgeon spawning conditions.

How close do the drones get to wildlife and people?

Manitoba wildlife regulations prohibit harassing wildlife, so we maintain the distance needed to avoid that, which varies with species and individuals. If we saw behaviours indicating an animal was being disturbed, we would quickly move further away. Our drones are very quiet and with the cameras we use, we don’t need to get close to an animal to see it in high detail.

We don’t intentionally get close enough to identify a person unless they have provided their consent.

What excites you most about the project?

I’m very excited by the amount of detail that can be obtained with a drone. We can create 3D images of an area, which will be very impressive for things such as depicting cultural or natural features on waterways.

When will the map be complete and where can I find it?

The map should be complete in 2023, following another field season in 2022. ECOSTEM holds the data and information for the map in trust for the Pimachiowin Aki communities. Because the map and derived products contain confidential information that belongs to the communities, they may only be used with the express and prior permission of the communities.

Species of Conservation Concern: Boreal Woodland Caribou

December 20, 2021

Across Canada, industrial activity and wildfires are changing forests and habitat for boreal woodland caribou. Pimachiowin Aki’s large stretch of intact boreal forest offers a rare haven for this majestic species—four groups of boreal woodland caribou live in the protected area, including one of Manitoba’s largest groups.

Boreal woodland caribou have been on the threatened species list in Manitoba since 2002. They were listed as a threatened species across Canada in 2003.

How Pimachiowin Aki meets the needs of boreal woodland caribou

Caribou Biologist Dennis Brannen, Wildlife, Fisheries and Resource Enforcement Branch of Manitoba Agriculture and Resource Development, explains that boreal woodland caribou thrive in Pimachiowin Aki, in part, because the vast landscape allows them to avoid predators. Boreal woodland caribou inhabit Pimachiowin Aki’s remote islands, peat bogs, and mature forest, which are typically not desirable for predators like wolves and species wolves prey upon, such as moose.

“Caribou exist in older mature forested areas where there is limited food types. Wolves have less reason to go into those areas because there’s less to feed them,” explains Dennis. Caribou are able to travel more easily in Pimachiowin Aki’s deep, persistent snow and wet peat bogs compared to wolves, he adds.

Pimachiowin Aki provides boreal woodland caribou with their preferred winter foods—lichens that grow on trees and the ground, typically found in spruce, pine and tamarack forests.

The human–predator domino effect, explained

Predators are not the root threat to Canada’s populations of boreal woodland caribou. “The general decline that we are seeing essentially comes back to human-caused landscape change,” says Dennis. Pimachiowin Aki has limited roadways and is protected from commercial mining, logging and peat extraction. In contrast, human activity across the country “has pushed the [caribou] population to the edges and restricted them to broken up patches of forests,” says Dennis.

Pimachiowin Aki is free from the adverse effects of industrial development.

When forest is broken into segments, it creates multiple issues for boreal woodland caribou. Dennis explains the domino effect.

“When forests are disturbed through human activity or natural causes like wildfire, regrowth is initially dominated by leafy shrubs, herbs and grasses—that new generation of vegetation is a surplus of food that leads to more primary prey species for wolves, such as moose.” Wolves follow and ultimately prey upon caribou, too.

Developments such as roads and trails also pose a threat. Dennis describes these linear features as “highways for predators.” They allow wolves to get into areas that were once less accessible, pick up speed, and prey on boreal woodland caribou.

Industrial development creates open areas in the forest, making boreal woodland caribou more vulnerable to predation.

Wolves are not caribou’s only predators. Other species will prey on them “when an opportunity presents itself,” says Dennis. “Across the boreal forest, black bears will prey on boreal woodland caribou calves. Out west in the Rocky Mountains, cougars prey on caribou, especially younger caribou,” he adds.

The climate change-predator domino effect, explained

Boreal woodland caribou travel well in wetlands. “When you bring climate change into the scenario, those wetlands become dryer,” says Dennis. In dryer times, wolves can get into those areas more efficiently. “This has implications for predation on caribou as well.”

Caribou birth rates

Another factor contributing to Canada’s declining boreal woodland caribou populations is that caribou don’t have as many young as other wildlife.

“Moose, elk and deer often have twins,” says Dennis, noting that this is rare in the caribou world. “Caribou will only have one offspring per year, so you end up in a situation where more [caribou] are being removed than added to the population in many cases.”

Ghosts of the forest—Caribou sightings in Pimachiowin Aki

Pimachiowin Aki Guardian Dennis Keeper reports seeing few caribou in Little Grand Rapids First Nation. “Fifteen to 20 years ago, we used to see hundreds and hundreds of them while traveling winter roads.” That is no longer the case. “I saw 14 of them two springs ago—a group of females. You don’t even see tracks now.”

Dennis Brannen suspects that caribou have started to avoid busier areas, like the winter roads. “Caribou are known as shadows or ghosts of the forest. They’re a secretive animal, so they don’t always show themselves when they’re around that landscape. They just shy away from where people are.”

Living with wildfire in Pimachiowin Aki

“Caribou have learned to live with fire [in Pimachiowin Aki] through time,” says Dennis Brannen. Fire is an opportunity for land to renew itself and create new and future habitats. “It’s only when we start increasing the amount of human disturbance on the landscape in combination with fire that we start seeing negative impacts on caribou populations,” he says.

But climate change could change that, warns Dennis. “With climate change, we potentially see an impact with the size of fires and frequency and intensity of those fires on landscapes. So, there are likely to be negative impacts to available habitat and population through time.”

Pimachiowin Aki is the largest protected area in the North American boreal shield. At more than 29,000 sq. km, it provides boreal woodland caribou with room to withstand the impact of fire-related habitat loss.

The future of boreal woodland caribou

Across Canada, people are combining western and Indigenous ways of knowing to protect boreal woodland caribou and their habitat.

“Our desire is to do a better job as we move forward to bring Indigenous knowledge into caribou conservation here in Manitoba,” Dennis shares.

Manitoba’s boreal woodland caribou recovery strategy sets out goals that align with Canada’s recovery strategy. A key goal is to manage and protect boreal woodland caribou habitat to sustain populations across the land. However, results will not happen quickly.

It’s a long-term process and we have to keep that in mind,” says Dennis. “We can’t just say, okay, we’re protecting undisturbed landscape and expect caribou to start doing well tomorrow. We need to look at opportunities and ways in which we can move disturbed habitat back into a state that is suitable for boreal woodland caribou use in the future.”

Research from across Canada indicates that when a habitat is disturbed by industry, for example, it takes roughly 60 years for that habitat to become useful to caribou again.

“We are constantly reviewing developments and proposals, and looking at how they may or may not impact caribou directly,” says Dennis.

There is hope for boreal woodland caribou. Last year, it was reported that the George River population (Labrador and Quebec) increased for the first time in 25 years. That area banned hunting of caribou in 2013. However, woodland caribou are not protected across the country. Their survival is tightly woven into the long-term health of boreal ecosystems, such as those of Pimachiowin Aki.

Anishinaabeg continue to provide wildlife, including threatened species like boreal woodland caribou, with healthy habitat. Here caribou will continue to feed in both winter and summer months and find safe spaces to calve and raise their young.
